GREASE Application filed May 21,

This invention relates to improvements in grease cellars.

Hercto'fore, in the lu'ln'ication of journals of locomotives, it has been the general practice to use a grease cellar-having a single wide chamber from 'w'hichthe greas je or other in bricant is dispensed. in such cellars a perl o rated dispensing plate is employee to bear against the under portion of the'journal and curved to conform therewith, the chord of the arc of such dispensing plate and the width of the chamber in which the plate moves corresponding approximately to the usual width between the aws of the driving box. Such types ot'grease ccllaii'shave proven unsatisfactory in many instances for the reasons that a necessarily large amount oi lnln'icant is used and there is no adequate provision'h'ir cooling ol the grease collar or the journal. l nrtherinorc, such types of cellars possess the further disadvantage that there are no means provided for collecting and removing removing removing the cellar irom the driving box.

Mo re specifically, an. object ot'niy invention is to providea grease cellar having a relativelyi'iarrow gr use -dispensing chamber and relatively shallow side chambers to collect the wastegrease, said collectingchambers being; provided with readily removable grease col.- lecting means whereby said means may be talcen out, the used grease renio ved theretrom and said means restored without talking down the cellar.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter iollowi ng.

F1gure'2 is a top plan. view of my improved grease cellar u detached l "-"n the drivin box, the one .ri'tiiie shallow CELLAR.

collecting chambers being omitted to more clearly illustrate certain parts of the grease cellar proper. Figure 3 is a vertical, sectional view corresponding substantially to the line 33 of Figure 2. And Figure 4 is a transverse, vertical SQCtlODEIl view corresponding substantially to the lin otFigure 2. in said drawing, A designates a locomotive driving box such as commonly employed on niany locomotives; B indicates the usual journal; and 0,111 y improved grease cellar proper.

The {driving box A, as illustrated, is provided \vith'the nsual brass 10 and depending side jaws 11*11, spaced apart slightly, more .han the dian'ieter ot' the journal B and between which jaws the improved grease cellar C isadapted to be inserted and retained in position.

The in'iprovcd grease cellar C, as shown, preferably consists of a casting having a relalively ,i'iarrow, horizontal. bottom wall 12, llOlil which extend upwardly, vertical side walls 13-13 and an integral. vertical end wall 14; on the outer end of the cellar. lllhe end wall let has its upper edge curved to conform to the curvature of the journal and side walls 13 extend to a point approximately 1 contact with the journal] At the bottom, the casting is provided with four icorner, lugs 15 15, spaced apart longitudinally o'ijthe cellar, as clearly illustrated in the plan view in Figure 2 so as to provide OPODlUgS or recesses 16 on each side of the side walls 13, the lugs being uni t ed with the con tral portion of the casting by webs 17-1'7. The four corner lugs 15 are apertnred as indicated at 18-1S, so as to receive retaining bolts 19 which are extended through-aligned openings in the depending jaws oil the driving box so as to secure the grease cellar in place as clearly evident from l igure 1. The bolts 19 may be retained in place by suitable cotters 20.

Formed intep'rally with the side walls 13 and extending laterally 1' rom eacluis an area ate web section. 21 on each side of the casting, the curvature'of which corresponds approximately to the curvatin-e ol the journal and is spaced a short distance therefrom as clearly shown in Figure t. The upper edges of the,

webs 21 are extended vertically as indicatcdat 22 so as to it against the jaws of the driving box and thereby assist in retaining the grease cellar in "place. At the outer end of the cellar, int l be i i hich, to

d walls 23 are provided w '1 l i the meet-ions ended and Ho the uppermost portions of the side walls 13, form shallow side chambers for the purpose hereinafter described. The said side chambers are further integrally connected with the remainder of the casting by vertical web reinforcing sections 2l2% oi' comparatively narrow width so as to leave spaces -25at each side of the cellar within the vertical 1 planes defined by the outermost portions of the sides of the casting for the purpose hereinafter described.

A movable or displaceable end plate 26 is secured to the inner end of the grease cellar casting, this being accomplished preterably by two bolts or screws 27'2'. threaded into tl c main casting and which pass through vertically elongated slot-s 2S-28 in the plate 26. The plate 26 is of generally rectangular outline in its lower portion and at its upper portion has the edge thereoi made arcuate as indicated at 29 to conform approximately to the curve of the journal and side arms 3030 are provided for the plate to close or cover the ends of the side chambers 23. It will be noted from an inspect-ion of Figure 1 that the plate 26 is of such contour that the spaces 25 at each side of the casting are open at the ends of the grease cellar and of the driving boX so that air may have access to said spaces in a directionlengthwise of the grease cellar. V r

- The bottom wall '12, side walls 13, integral end wall 14 and plate 26, together constitute a central chamber fromwhich the grease or other lubricant is adapted to be dispensed. This chamber, as clear from an inspection of Figure 4, is relatively narrow. In the central dispensing chamber is provided a perforated grease dispensing plate 31, the upper main port-ion of which is curved to conform to the journal and has depending side flanges 3232 slidably guidedby the inner faces of the side walls 13, the latter preferably being rabbeted or recessed at their upper portions, thus forming shoulders 33 to limit the down- -ward movement of the plate 31 as will be evident.

Also disposed in the central chamber is a follower plate an adapted .to be yieldingly pressed upwardly by two or more coil springs 35 interposed between the plate 3% and the bottom wall ot' the casting. Acake ot'grease as indicated at 36 is interposed between the follower. plate 3% and the dispensing plate 31 so that the grease cake will be pressed upwardly against the plate 31 and the latter, in turn pressed against the journal. Telltales 37 may be attached to the follower plate 34 and extended downwardly through suitable openings 38 in the bottom wall of the casting so as to indicate the thickness of the grease cake at'any time without necessity of taking down the cellar. The telltales also are used to pulldown the follower plate when renewing the grease cakeing lip or flange 40i0.

By loosening the bolts 27, it is obvious that the end plate 26 may be dropped down without actually detaching it from the cellar casting and, inthis position of the plate 26, a new grease cake may be inserted or the old one taken out and, likewise, pans or collecting plates 39 may be inserted or removed, without, the necessity of taking down the grease cellar as an entirety.

By making the central dispensing chamber relatively narrow, the lubricant is applied over a much narrower area than has heretofore been the general practice and experience has demonstrated that a much more economical use of grease is thereby accomplished. Furthermore, the narrow central chamber leaves relatively large spaces on each side of the casting which, in combination with the longitudinally spaced corner lugs 15, permits or" ample air circulation vertically on each side of the central chamber, this circulation being augmented by the provision for longitudinal air. circulation as hereinbefore referred to, thus bringing the air against the bottoms of the shallow side chambers and hence to a point closely adjacent the journal to thereby provide for effective cooling of the latter. i

The grease is dispensed from the central chamber in the manner heretofore indicated, and depending upon the manner of rotation of the journahthe used or waste or -arried'over grease is collected ineither or both of the shallow side chambers and on the pans 39. YVhen it is desired to clean out the waste grease, it is only necessary to lower the end plate 26,'pull out the pans 39, scrape them oil and return them to position, which obviously canbe done in a very short time and with very little labor.

To lighten thecasting, the bottom walls or webs 21 of the side chambers may be provided with enlarged openings 40-4C1, which openings will obviously be covered by the pans 39 when the latter are in place.

From the preceding description, consideredin connection with the drawing, it will be seen thatI have provided a light, selfcooling cellar with provision for economical dispensing of the lubricant and with simple and convenient means for maintaining the proper condition of the cellar at all times without the necessity of removing the cellar from the driving box.

I have herein shown and described what I now consider the preferred manner of earrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

1. A lubricating cellar for locomotive driving boxes comprising: a member having a chamber in which the lubricant to be dispensed is adapted to be contained and a separate chamber therefrom; and removable means in the last-named chamber forming a part of said chamber and adapted to collect the used lubricant whereby used lubricant may be removed by removing said means from the cellar.

2. A lubricating cellar for locomotive driving boxes comprising: a member having a chamber in which the lubricant to be dispcnsed is adapted to be contained; and a separate chamber, said chamber being open at one end; removable means disposed in said last named chamber for supporting lubricant collected in said chamber, said means being endwise removable thiiough said opening; and displaceable means at one end of the cel lar for closing said opening and retaining said first named means in position.

3. A lubricating cellar for locomotive driving boxes comprising: a member having a central chamber and two side chambers, one on each side thereof; and removable means in each of said side chambers and forming a part thereof on which the waste lubricant is adapted to be collected and removed from the cellar.

4. A grease cellar for locomotive driving boxes comprising: a member having a cen tral-grease-dispensing chamber and two side collecting chambers each open at one end; removable means in each of said side chambers on which the waste grease is adapted to be collected, said means being removable through the open end of each of said chambers; and displaceable means at one end of said chamber for closing said openings and retaining said first named means in place.

5. A grease cellar comprising a casting having a relativelynarrow central chamber defined by side walls, a bottom wall and end walls and two integrally formed shallow side chambers extending in a general direction laterally and upwardly from the upper parts of said side walls oi": the central chamber, the

bottom walls of said side chambers having openings therein, removable means for closing said openings, said rei'novable, means forming a support for collecting the lubricant the cellar having spaces at each side of the central chamber to thereby permit circulation of air therein when the cellar is in place in the usual driving box.

6. A grease cellar for locomotive driving boxes comprising: a casting having a relaner lugs arranged in pairs spaced longitudinally; a central chamber integrally formed therewith and defined by a bottom wall and vertical sidewalls and an integral end wall; and relatively shallow side chambers defined by integrally formed sections, the casting being provided with spaces on opposite sides of said central chamber; collecting plates, onein each of said side chambers; and a plate movably attached to one end of said casting and adapted to close the adjacent ends of said central and side chambers,.said plate being oft restricted Wldtll at its lower portion.

In witness that I claim the foregoing I have hereunto subscribed my name this 17th day of May, 1927.
